Post-1906 Naturalization records moving to U.S. National Archives

Naturalization records maintained by the Bureau of Citizenship and Immigration Services since 1906 will be transferred from the Department of Homeland Security to the National Archives and Records Administration beginning in 2010. Public access will be available if the immigrant has passed away or turned 100 years old. Previously, these files were available through a laborious Freedom of Information Act request as explained in our guide to Naturalization and Citizenship Records.
